That s because weirdly collecting rainwater is actually illegal in some states.
Here are a few with specific rules governing rainwater harvesting.
Such water does not go bad at all.
However like with many things there are rules and ordinances at the state level that may affect you.

But for groundwater harvesting regulations are.
The barrel should have a spigot to which a hose may be attached and an overflow hose.
